Questions: Rocks are folded. Horizontal rocks are deposited over eroded tilted beds. Rocks are deposited horizontally.

The answer is:

1. Rocks are deposited horizontally.
2. Rocks are folded.
3. Horizontal rocks are deposited over eroded tilted beds.

Explanation:

1. Rocks are deposited horizontally: This is the initial stage where sedimentary rocks are laid down in horizontal layers.

2. Rocks are folded: After the initial deposition, tectonic forces cause the horizontal layers to fold, creating tilted beds.

3. Horizontal rocks are deposited over eroded tilted beds: Following the folding, erosion removes the upper parts of the tilted beds. Subsequently, new horizontal layers of sedimentary rocks are deposited on top of the eroded, tilted beds, forming an angular unconformity.
